Thanks for answer. I have following jars in the endorsed library. jbossws-native-jaxrpc.jar,-jaxws.jar, -jaxws-ext.jar, -saaj.jar, Exception is : Exception in Thread main javax.xml.ws.WebServiceException : No Content-type in the header at com.sun.xml.ws.transport.http.client.HttpTransportPipe.process(HttpTransportPipe.java 163:) at com.sun.xml.ws.transport.http.client.HttpTransportPipe.processRequest(HttpTransportPipe.java ) at com.sun.xml.ws.api.pipe.Fiber.__doRun et.c.... I run the client in standalone mode in Eclipse. Actually, I am putting all the JBoss Client jars in to the class path. Exactly, which jars that I have to setup in the client classpath to call webservice correctly?
